Each command is listed, in detail, in the following sections.
config name_server
Purpose Used to configure the DNS Resolver name server of the switch.
Syntax
config name_server [[add |delete ] <ipaddr> {primary} | timeout <second 1-60>]
Description The config name_server command is used to configure the DNS Resolver name server of the
switch. Note that only when add a name server, the parameter “primary” will be resolved.
Other conditions won’t resolve the parameter “primary”. It means that when delete a name
server, just check the IP address. If the IP address is the same to the name server’s, the
name server will be deleted, don’t check the priority parameter.
When adding a name server, if one primary name server exists in the static name server
table, then add a new primary name server, the existing primary name server will be changed
to a normal name server. If the added primary name server’s IP address is the same to an
existed normal name server’s IP address, the existing normal name server will be changed to
a primary name server, but won’t add new name server. When no primary name server is
specified, the first configured name server will auto change to primary name server.. If the
deleted name server’s IP address equals to one of the existing name servers’ IP addresses,
regardless whether a normal name server or primary name server, the name server will be
deleted.
